CHEETAH
La série Cheetah est conçue à partir d'un détecteur InGaAs refroidi, développé en interne, d'une résolution de 640 x 512 pixels et d'un pas pixel de 20 µm. Disponible avec un détecteur refroidi single-stage TE-cooled, elle offre des fréquences d'images exceptionnelles de 400 Hz, 800 Hz ou 1700 Hz, tandis que l'option avec un détecteur three-stage TE-cooled permet d'atteindre une fréquence d'images de 110 Hz. La série Cheetah est proposée avec une interface CameraLink et est disponible avec une option infrarouge visible à ondes courtes (vSWIR) pour une extension dans le spectre du visible.
Imagerie SWIR la plus rapide au monde, jusqu'à 1700 Hz
Faible bruit, faible courant d'obscurité
Transfert de données fiable par CameraLink
